I'm having problems running python3 with cv2.
When I try to run an script with cv2.namedWindow I get "OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /io/opencv/modules/highgui/src/window.cpp, line 565"
I have configure opencv 3.2 with this flags:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_GTK=ON -D WITH_OPENGL=ON ..
But allwais fail.
I think that I have a problem in the installation.
sudo -H pip3 install cv2
In the summary of the cmake I can read:
-- General configuration for OpenCV 3.2.0-dev =====================================
-- Version control: 3.2.0-373-gf109c01

-- numpy: /usr/local/lib/python3.5/dist-packages/numpy/core/include (ver 1.12.1)
-- packages path: lib/python3.5/dist-packages
But inside python3 with
>>> import cv2>>> print(cv2.getBuildInformation())
I get:
General configuration for OpenCV 3.2.0 =====================================
Version control: 3.2.0

QT: NO
GTK+: NO
GThread : YES (ver 2.12.3)

VTK support: NO
I dont know how to tell python3 to use my opencv compilation. I did make; make install and I have opcencv2.4 installed with apt-get.
